12 Example exshade
13
15 This program demonstrates how to draw Gouraud shaded (lit) sprites. In
16 an apparently black screen, a planet like sprite is drawn close to the
17 middle of the screen. In a similar way to how the first test of extrans
18 works, you move the cursor on the screen with the mouse. Attached to
19 this mouse you can imagine a virtual spotlight illuminating the scene
20 around. Depending on where the mouse is, the Gouraud shaded sprite will
21 show the direction of the light.
